From the Journals of Gubin Turnipheed

This tome, the third in a series of guidebooks by the legendary Wanderers Guild, is a collection of essays and expositions by the renowned Gubbin Turnipheed. Gubbin has noted down his findings over the years of his exploration across the known, and some unknown lands, with his "companion" young Matron Grubb etching what he finds in his on "special" style. Here you will find detailed narrative and remarkable depictions of the creatures and races, herbs and useful plants, peoples and gods that Gubbin has encountered on his travels.

Matron's etchings have been converted to a more distinguishable style by Guild Illuminator Scott Purdy and Gubins' original manuscripts translated by master scribe Andrew Troman. This d20 system source book has been brought together to ensure those traveling across the wilds are equipped with the knowledge that not all that is green is edible. Some of it may well be doing the eating.
